Abstract

The design of large-scale complex systems requires their analysis from multiple perspectives, often through the use of requirements models. Diversely located experts with different backgrounds (e.g., safety, security, performance) create such models using different requirements modeling languages. One open challenge is how to align these models such that they cover the same parts of the domain. We propose a technique based on natural language processing (NLP) that analyzes several models included in a project and provides suggestions to modelers based on what is represented in the models that analyze other concerns. Unlike techniques based on meta-model alignment, ours is flexible and language agnostic. We report the results of a focus group session in which experts from the air traffic management domain discussed our approach.

Tez (Yüksek Lisans) -- İstanbul Teknik Üniversitesi, Fen Bilimleri Enstitüsü, 1998 Thesis (M.Sc.) -- İstanbul Technical University, Institute of Science and Technology, 1998 Bu çalışmada son yıllarda ulaştırma sektöründeki gelişmeler değerlendirilmiş, özellikle Avrupa’da AB oluşumunda ulaştırma sektörüne yönelik SK prensibiyle oluşturulan politikalar ve gözlenen gelişmeler, uluslararası ulaştırma koridorları, kombine taşımacılığa verilen önem belirtilmiştir. Bu bağlamda Türkiye’de ekonomik gelişme ve ulaştırma sektörünün konumu değerlendirilmiş, Avrupa’yla ilişkiler bazında ulaştırma sektörünün gelişimi üzerinde durulmuş, Türkiye’nin de dahil olduğu uluslararası koridorlardaki kombine taşımacılık altyapı ve trafik yönünden incelenmiştir. Konunun Avrupa’yla bütünleşme boyutunda değerlendirilmesinde, Türkiye’nin AB üyeliği tartışmalarından bağımsız olarak, Avrupa’yla ekonomik ilişkileri yönünden olumlu sonuçlar elde edilebilmesi için fiziki altyapı, ekonomik ilişkiler, finansman, politika ve hukuki uyum kriterlerinin önemi vurgulanmıştır In this study, the policies developed in EU concerning the transportation sector and the realised developments, multimodal international transport corridors, combined transportation concern are mentioned.
